Pardon...I do not speak French....how do the French decide whether a new invention is Masculine or Feminine?

no gov dept on that...but the Académie Française

It's the " Académie Française " who decides

It depends on the sexe of the inventor. Lol.

More seriously, the "new" word is already used by the people as a feminine or a masculine one before it is officially accepted.

Good question.

i think people decides. The first ones who write the word in french after find it in an English site, as "a blog" become "un blog".

In a second time, the academie Francaise officialise this choice or find another word, as an email which is not a french word. Academie Francaise says "use courriel for that", but nobody use that.

Simply, if the inventions have bowls and a dick, it's a male, either it's a female.

That is a good question. Frankly, I really don't know how to answer your question. I'm bilingual, English-French. The only observation I have is that it's innate. For example: we say, la maison (house), feminine and not le maison. I think it's a question of logistics. The brain corrects a word whether or not it's masculine or feminine.

no i think that they take the word as in english
